Abstract: The mechanical transmission performance is one of the most important issues in the field of parallel mechanism. Based on the concept of transmission angle, this paper takes a PRRRP symmetric parallel mechanism as the research object, puts forward a measurement index to evaluate the force transfer performance of the planar parallel mechanism, and uses this index to optimize the corresponding design of the PRRRP symmetric parallel mechanism.
Keywords: parallel mechanism; optimal design; transmission angle
